Acopy machine depricicates at the rate of 15% each year. if the original cost fo the copy machine was $20,000 , what is the approximate value of the machine after 3 years

The approximate value of machine after 3 years = $12283

Step-by-step explanation:

Original cost of the copy machine = $20,000

Rate of depreciation each year = 15%

To, find cost of machine after 3 years.

Solution:

The depreciation equation can be given by:

where:

Final value

Original value

rate od depreciation in decimal form

time

Given values:

Using the values to find the value of machine after 3 years.

Thus, approximate value of machine after 3 years = $12283

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
